Definitions

  • the present invention relates to a stent for prostatic urethra expansion, and more particularly to a stent for prostatic urethra expansion which does not generate bladder stones, is removable without causing injury on a urethra, and does not generate atrophy of a prostatic urethra even after removal.
  • prostatism was generally defined as an enlarged prostate which gets fat, blocks a discharge passage of urine under a bladder, and thus causes urethral obstruction to reduce a urine flow.
  • prostatism is defined as proliferation of stromal cells or epithelial cells of the prostate.
  • prostatism is defined as lower urinary tract symptoms including bladder storage symptoms, such as pollakiuria representing a state that a male who is 50 years old or more abnormally frequently discharges urine more than 8 times or more a day, nycturia, and urgency representing a state of being incapable of holding urine while having strong and sudden desire to urinate, and bladder dysfunctions, such as delay (a state of discharging urine after a designated time), interruption (a state of interrupting a urine flow), and pushing during urination.
  • bladder storage symptoms such as pollakiuria representing a state that a male who is 50 years old or more abnormally frequently discharges urine more than 8 times or more a day
  • nycturia and urgency representing a state of being incapable of holding urine while having strong and sudden desire to urinate
  • bladder dysfunctions such as delay (a state of discharging urine after a designated time), interruption (a state of interrupting a urine flow), and pushing during urination.
  • Such prostatism is treated with aerotherapeutics and pharmacotherapy.
  • pharmacotherapy requires a considerably long time, and pain due to prostatism continues to occur during treatment using pharmacotherapy.
  • the present invention has been made in view of the above problems, and it is an object of the present invention to provide a stent for prostatic urethra expansion which does not generate stones, does not move to the inside of a bladder, and expands and maintains a lumen of a stenosed prostatic urethra.

  • a pair of hanging strings 30 is arranged in opposite directions such that the hanging strings 30 pass through the space parts 12 of the end of the cylindrical body 14 at which the hooks 21 are formed and are hung onto the bending terminals 13.
  • the hanging strings 30 are knotted together, thus forming a hanging knot 31 located at the center of the cylindrical body 14.
  • the hanging knot 31 is located at the center of the cylindrical body 14, and, when the hanging knot 31 is pulled to remove the stent unit 10, the stent unit 10 is extended in the lengthwise direction and the diameter of the stent unit 10 is reduced. Thereby, the stent 100A for prostatic urethra expansion is obtained.
  • a stent 100B for prostatic urethra expansion in accordance with another embodiment of the present invention serves to expand and maintain a lumen of an organ of a human body stenosed due to lesion, and a stent unit 10 is formed.
  • the stent unit 10 includes a cylindrical body 14 provided with space parts 12 formed by knotting or crossing, in a zigzag shape, one or more strands of shape memory alloy wires 11, and a plurality of bending terminals 13 formed at both ends of the cylindrical body 14 along the circumference of the cylindrical body 14.

  • the stent 100A or 100B for prostatic urethra expansion is surgically operated using a separate stent insertion apparatus 400 (only the stent 100A for prostatic urethra expansion is illustrated in the drawings).
  • a guide wire W together with an endoscope 300 is inserted into a lesion part 201 of a prostatic urethra 200 through a urethra of a patient.
  • the endoscope 300 is removed, and a part of the guide wire W maintains a state exposed to the outside of the patient's body.
  • the guide wire W passes through the inside of the front end of the fixed tube 401 and the inside of the front end of a moving tube 402 moving forwards and backwards in the fixed tube 401, thereby enabling the stent insertion apparatus 400 to be inserted into the urethra within a penis of the patient.
  • the front end of the fixed tube 401 is located in the rear of the lesion part 201 of the prostatic urethra 200, and then the moving tube 402 moves forwards to push the stent 100A or 100B for prostatic urethra expansion out of the fixed tube 401.
  • the stent 100A or 100B for prostatic urethra expansion pushed by the moving tube 402 and then exposed, is expanded in volume and restored to its original shape, and thus pushes the prostatic urethra 200 stenosed by the lesion part 201 outwards and expands the lumen of the prostatic urethra 200.
  • the hooks 21 are hung onto the luminal wall of the prostatic urethra 200. Thereby, the stent 100A or 100B for prostatic urethra expansion is not introduced into the bladder B of the patient due to movement of the patient.
  • the operated position of the stent unit 10 is configured such that the hanging knot 31 is located at the lower part and the hooks 21 face upwards.
  • the stent insertion apparatus 400 and the guide wire W are removed through the urethra.
  • the stent 100A or 100B for prostatic urethra expansion expands the prostatic urethra 200, thus assisting smooth discharge of urine.
  • the stent 100B for prostatic urethra expansion enables the membrane 40 to prevent tissues of the luminal wall of the prostatic urethra 200 from coming into direct contact with the stent,unit 10 and from growing into the stent unit 10 through the space parts 12 and then being stenosed to the stent unit 10.
  • the stent 100A or 100B for prostatic urethra expansion is removed.
  • the stent insertion apparatus 400 is inserted through the urethra along the guide wire W, under the condition that a separate removal wire 403 in the shape of a hook is inserted into the end of the moving tube 402 of the stent insertion apparatus 400, and is located in front of the hanging knot 31.
  • the stent 100A or 100B for prostatic urethra expansion is pulled by the hanging strings 30 and the volume of the stent 100A or 100B for prostatic urethra expansion is reduced, and thus the stent 100A or 100B for prostatic urethra expansion is inserted into the fixed tube 401 while separating the hooks 21 from the luminal wall. Then, the stent insertion apparatus 400 is removed from the body of the patient. Thereby, the removal operation of the stent 100A or 100B for prostatic urethra expansion is completed.
  • the present invention provides a stent for prostatic urethra expansion which does not generate stones, does not move to the inside of a bladder, and expands and maintains a lumen of a stenosed prostatic urethra, thereby reducing postoperative recovery time.
  • a membrane is fastened to the external surface of a stent unit so as to prevent luminal tissues of the prostatic urethra from being stenosed to the stent unit, thereby preventing induction of secondary injury during removal of the stent unit.
